I also try to follow the 1 controller - 1 device rule. The motherboards with onboard raid are even better. You can have 4 HDs on individual controllers. All of my systems have /, /usr/src, and /usr/obj on different HDs for performance.

The new round ATA-133 cables even get rid of the air flow problem.
They are typically 24 inches long instead of the 18 inches max on the
ribbon cable.
